CTAS on a Table with Nested Tables

The other day one of my colleagues asked me if it is possible to create a copy of a table with all the content in it. He wanted to do some experiments with it and didn’t want to mess with the original table. A simple CTAS (Create Table As Select) didn’t work, because the table had a column which was a Nested Table.

Alex, as far as I know (tested a year ago), although XMLType is a “type” has the posibility of IOT’s and nested table storage etc (using create table test of xmltype,etc), can not be copied via CTAS. Could you have a check via your method? THX.
